To all whom/ it may concern.-

' Be it known that I, QLE MEDHUs, a citize of the United States, and aresident of the city of Faribault, in the county of Rice, and the Stateof Minnesota, have invented certain new and useful Im rovcments inCombination-Tools, of whic 'the following is a specification, which whentaken in connec tion with the accompanying drawings, forming-apart'thereof, is sufficiently clear and conciseas toenable othersskilled in the-art to which it appertain's to make and use the same;

PIA particular object of -my inventionis to provide a tool havingdetachable and intern-.-

c liangeablefpairs of jaws, whereby agreat var etyofwork maybe done anda great vaof material operated upon with a single for a large assortmentof tools, asnow used in many'trades-andoccupations.-

only to accomplish the; eb'ects stated in the preceding paragrapln, u talso to provide a tool in which the changes; or; transfers may be easilyand uickly made, even by one unfamiliar with "t eoperation of'devices ofthis character.

, The distinctive features of my invention,

briefly stated, consist of a pair of lever-han files, a plurality ofpairs ofjaws, each pair being'especially ada tedfor a different varietyof work, the nove means I employ for connecting the handles to thevarious pairs of jaws, the'arrangement of two pairs of jaws u on-ja. sinle pair 'of shanks, and the means f r ass'e'mb g the parts into acomplete tool. 3 My invention ,consists in a combinationtool embodyingnew and useful, features and .details of construction and the relativedisposition of the severalparts, substantially as articularly describedelsewhere in this specidcation, and in the legitimate combinationsherein set forth. Y A

One manner of carrying out my invention, that which in practice has beenfound the most desirable, is illustrated in the accompal'iyingldrawings, in which Q Figure ,1 is a side elevatlon of myassembleld tool, showing .two pairsof jaws, one pair being in operativeposition. 5} '-'%viewoffsame. parts shown in Fig. 1.

Lpplicatipn filed August 18, 1905 Serial No. 274664 -various parts andoperation as thereby dispensing with the necessity 'ing t Patented April3, lens.

elevation of a set of-doublepairs of jaws, united by their respectiveshanks, shown in their operative, position with reference to each other,the two parts being identical in construction. Fig. 8 is a plan view ofsame parts'as shown in Fig. 7, and Figs. 9 and 10 are perspective viewsof two identical parts containing two pairs of jaws and being adapted tobe operated in conjunction with each other.

Similar indices refer to and denote like -parts throughout the severalviews of the drawings. a

With all of the above-designated views in mind I will now take up thedetail description of 'my invention and will describe the briefly andcompactly as I may.

' In the drawings, the numeral 1 denotes the upper, or left-hand handle,and the figure 2 denotes thelower or right-hand handle, the two formingthe one pair of-handles for va-' rious combinations of tools. The saidhandles are of peculiar contour, their inner ends bein somewhatflattened and circular, formhe heads a and b, respectively, and thenextending back in oppositely-disposed outends parallel and lying oneabove the other, substantiallyas shown in Fig. 2.

Formed'on the inner face of the head a is the square fiatfaced lug c, asshown in Fig. '3, and formed transversely and centrally ward and theninward curves, with their free through the head a and the lug c is theround.

aperture d. Formed on the inner face of the head I) is the squareflat-faced lug e, as shown in Fig. 4, and formed transversely andcentrally through the head I) and the lug e is the square aperture In Fi-.-7 I have having t e jaws 3 and 3 havin the shanks 4 and 4 crossingeach. other and terminating in the oppositely-disposed taper-nose pliershaving the janvs 5 and 5 it being understood that the jaws 3 and 5 areintegral, being united by-the shank 4, and also that the jaws 3 and 5are integral, bein unitedby the shank 4". The shanks 4-an 4 areidentical in construction, but are oppositely disposed with reference toeach other, each having a square socket 72. and h, 'respectively,- inits outer face, whichsockets are of infinitesimally lar' .er' dimensionsthan are the lugs c and e,

.which are adapted to fit snugly therein. The .depth of said sockets issubstantially oneshown cutting nippers 9 5 IGO half the thickness ofsaid shanks, and continue ing on through the shanks fromsaid sockets areround apertures 12 and 7c, respectively.

It will now be apparent that the shanks for the other pairs of tools(shown in Figs. 1, 2, and 9, 10) are identical with the shanks of thetools shown in. Figs. 7, 8, and for convenience of description aresimilarlyindicated, the only difference in said. parts being the shapeof the working parts at the ends that is to say, the jaws 6 and 6 (shownin Figs. 9 and 10) may jaws 7 and 7) may be round-nose pliers. In lkemanner the jaws 8 and 8 in Figs. 1 and 2 may form wire-grips orpipe-wrenches, while their consorts (the jaws 9 and 9) may formfiat-nose pliers.

The numeral 10 denotes the transverse bolt having a permanent integralhead on one end thereof, the opposite end being threaded and on whichthreaded portion the knurled tap 11 may be run. A portion of the shankof the bolt 10 is formed round and a portion is formed squareincross-section, the round portion extending from the head being of alength substantially the same as the combined thickness of the head aand one and one-half times the thickness of one of the shanks 4 or 4',and from saidround portion the shank of the bolt 'is square, saidjsquareportion being slightly less in length than the thickness of the head band one-half the thickness of the shank 4 or 4. By reason of the squareportion of the shank of the bolt it should be noticed that the squareaperture f will fit thereover when the parts are assembled, whereby asthe handles are operated the handle 2 will at all times move the bolt 10and the tap 11 therewith, and thus ell'ectually preventing the tap 11from working loose from its contact with the handle 2.

It will now be seen that any two sets oi the tools may be broughttogether, as in Figs.

7 and 8, and the handles brought to the posi-' tions shown in Figs. land2, entering the lugs c and e in the respective sockets h and h. Then byinserting the bolt 10.tlnough the apertures d, 7c, 7s, and f in theorder named and running the tap 11 tightly on the threaded portion ofthe bolt 10 the parts will be assembled substantially as shown in Figs.1 and 2 and whereby as the handles are moved apart or toward each othera corresponding motion will be given to the jaws when in position as inFigs. 1 and 2. It will also be noticed that by removing the knurled tapl1 and then the handle 2 the tools then in the device may bereversed-that is, causing the jaws 8 8 to exchange position with thejaws 9 9, after which the handle 2 and the ta 1 1 may be relaced, asbefore, or, if desire after the hanle 2 and the tap 11 are removed anentirely different set of pairs of jaws may be posiform flat-nosepliers, while their consorts (the invention and the best means for itsconstruction to me known at this time, what I claim, and desire tosecure by Letters Patent ofthe United States, is

1. A combination-tool consisting of a plurality of double pairs of jawseach two pairs of said jaws being united by a pair of shanks crossingeach other with s uare sockets formed in their outer faces an roundapertures extending transversely through said shanks and central of saidsockets, a pair of handles having fiat heads on their inner ends withtransverse apertures formed therethrough, the apertiire in one of saidheads be ing round and the aperture in the other head being square, lugsformed on the inner faces of said heads of the handles which lu s areadapted to fit into said sockets in the shanks of the jaws, a bolthaving a permanent head on one end the other end being threaded with itsshank adapted to extend through said apertures in the shank and theheads of the handles, one portion of the shank of the bolt be ing-formedsquare to fit in the square aperture of one of the heads of one of thehandles, and a knurled tap adapted; to be run on the threaded portion ofsaid bolt to bind the parts together, all substantially as set forth.

2. A combination-tool embodying two pairs of jaws, a pair of shanksintegrally con necting the pairs of jaws, with apertures extendingtransversely through the shanks in the center of-their crossing-points,and with" a square socket formed in the outer face of each shank centralof said apertures, a pair of handles having flattened heads from whichthey extend in outward and inward oppositel -disposed curves with therear portions of t e handles parallel with each other, a square lugextending in from the face of the head of each handle which lugs are ofa size to fit said sockets in the jaw-shanks, a bolt for connecting theshanks of the jaws with the handles, a tap for retaining the bolt inpos1- tion, and means for preventing the turning of the nut by theoperation of the handles, all substantially as shown and described.

In testimony whereof .I have hereunto signed my name to this specificaton, n the signed my name to this speclficatlon 1n the presence ofv twosubscribing wltnesses, this the 12th day of August, .1905. I
